The Jets sustained another injury at corner in Monday's practice as undrafted rookie Kyron Brown left the field with a hamstring injury one day after starter Trumaine Johnson injured his own hamstring. Johnson underwent an MRI and his status for the regular-season opener against the Buffalo Bills is in jeopardy.

"I don't think it will be months," head coach Adam Gase said. "But, I mean, we'll see. It's week-to-week right now. It'll be about how his body responds to the rehab."

The Jets had entered training camp with concerns about the cornerback position after opting not to re-sign starter Morris Claiborne, who recently signed with the Kansas City Chiefs. Instead, their top three corners were Johnson, Darryl Roberts (16 career starts) and Brian Poole, who is in his first season with the Jets after three seasons with the Atlanta Falcons.

But Gase refused to show signs of panic despite the injuries.

"I look at it as Trumaine is down right now," said Gase. "This is a great opportunity for a lot of guys. Like somebody has a chance to step up and make a name for themselves. Somebody has a chance to get in with that first defense, go against our wide receivers, go against our offense and Sam (Darnold) and those guys and see if a guy can play at that high level."

Brown was replaced by 26-year-old Arthur Maulet, an undrafted free agent with limited experience in two seasons with the New Orleans Saints and Indianapolis Colts. Derrick Jones, a 2017 sixth-round pick, was waived by the Jets on Saturday.
